DOOR-HANDLE.

Specification of Letters Patent.

Patented Dec. 21, 1915.

Application filed August 27, 1914. Serial No. 858,871.

To all whom it may co ncern:

Be it known that I, W1LL1AM PATON, a subject of the King of Great Britairnand resident of the town of Longford Mills, county of Ontario, Province of Ontario, minion of Canada, have invented certain new and useful Improvements in Door- Handles, of which the following is a specification.

The invention relates to improvements in door handles as described in the present specification and shown in the accompanying drawings that form part of the same.

The invention consists essentially of the novel means employed for fastening the shalpks of the knobs to the door in a mortised loc c The objects of the invention are to devise a form of handle which will constantly retain the knobs in a fixed position longitudinally vent rattling and accidental displacement of the knobs, to construct a simple form of door 7 handle that will lend itself readily to adline D-D in Fig. 2.

justment and generally to provide a cheap, efiicient and durable door handle.

In the drawings, Figure 1 is a perspective view showing one door knob and shank partly broken away disclosing the adjusting mechanism also partly broken away and a portion of the spindle. Fig. 2 is a longitudinal sectional view of the invention showing it attached to a door. Fig. 3 is a cross sectionalview on the line 13-15 in Fig. 2. Fig. 4 is a cross sectional view on the line A-A in Fig. 2. Fig. 5 is a cross sectional view on the line BB in Fig. 2. Fig. 6 is a cross sectional view on the line (3-13 in Fig. 2. Fig. 7 is a cross sectional view on the Like numerals of reference indicate corresponding parts in each figure.

Referring to the drawings, 1 is the door knob having the shank 2 and the threaded spindle hole 3 in said shank leading inwardly from the bed of a squared recess 4.

5 is a spindle having straight sides 6 intermediate of its cross section or otherwise for a portion of its length and at either end having the corners of the squared shape beveled and threaded as at 7 leaving the flat surfaces 8.

9 is a sleeve having the reduced squared portion 10 slidably mounted on the fiat surfaces 8 of the spindle 6 and the larger portion 11 circular in shape. The reduced end length, that is to say of square in the Doin relation to the door and thus pre-v being 10 is slidably mounted on the flatsurfaces '8 and fits into the correspondingly squared recess4 so that said sleeve 9 turns with said shank 2 and consequently the spindle 5 turns with the turningof the knob 1.

. 12. is a thimble screw threaded onto the spindle 5 beyond the shank 2 and having the circular flange 13 at one end thereof.

14 is a helical spring encircling the periphery of the thimble 12. The thimble 12 is telescopically arranged in the sleeve 9, the end of said sleeve engaging the spring 14, the latter forming a cushion bearing for said sleeve.

15 is a knob having the shank 16, said shank having a threaded spindle hole 17 into which the other end of the spindle fits, held therein by the sleeve 18 slidably mounted on the spindle and having the squared end 19 which fits into the recess 20 in the shank 16. The holes in the door 21 are made to suit this device being little different from the present practice.

v 22 are plate shields encircling the shanks of the knobs and secured to the door.

It will be seen that in installing these door handles, the spindle is first inserted in the knob 15. The other end of the spindle is r then inserted through the door and through shank has reached the sleeve 9, said sleeve is grasped and drawn up over the thimble 12 thus compressing the spring 14, then while the sleeve 9 is in this position the shank 2 is screwed up until it again reaches the said sleeve. On releasing the grip from said sleeve the spring 14 forces the squared portion 10 back into the recess 4 of the shank 2 and thus prevents it from being removed until the spring is agaln compressed by drawing the sleeve up on to the thimble. When these parts have been adjusted the shield 22 which has previously been slipped over the shank 2 and uptoward the knob, is brought back and securely fastened to the door in the usual way.

What I claim is:

In door handles, a pair of knobshaving shanks provided with squared recesses in their ends and threaded holes extending in- Wardly from the beds of the squared recesses a spindle having into the corresponding recess in the other knob sliding on said spindle and forming an annular recess between itself and'said spindle; a'thimble having a flange at its inner end 7 'dayof June 1914..
